Technical Information - Preliminary Revision 1.0 – December 2002
G E N E R A L D E S C R I P T I O N
The TK2150 (TC2001/TP2150 chipset) is a two-channel, 200W (6
) per channel Amplifier
Driver that uses Tripath’s proprietary Digital Power Processing (DPP
) technology.
Class-T amplifiers offer both the audio fidelity of Class-AB and the power efficiency of
Class-D amplifiers.
